1. What is the bean-shaped retroperi- kidney
toneal organ that is around 12 cm
in legnth
2. what are the major parts of the kid- cortex, medulla, and renal pelvis
ney
3. what is the cortex outer region of kidney
4. what is the medulla inner region of the kidney
5. what is the renal pelvis funnel shaped region, continues to ureter
6. what is the function of the kidneys vary excretion of water, electrolytes, and other mole-
cules to maintain consistency of ECF composition
7. what 4 things do the kidneys partic- multiple endocrine functions, BP control, acid-base
ipate in control, and bone marrow stimulation for RBC produc-
tion
8. What is the functional unit of the nephron, 500-800k per kidney
kidney and how many are there per
kidney
9. what does the nephron consist of glomerulus, bowmans capsule, proximal tubule, loop
of henle, distal tubule, collecting duct, and the renal
pelvis
10. what happens in the glomerulus primary site of urine formation, where blood plasma
is filtered into the nephron
11. what happens in the bowmans cap- upper part of nephron, collects filtrate from glomeru-
sule lus

12. what does the proximal tubule con- convoluted and straight portions
sist of
13. what is the loop of henle continuation of proximal tubule and it contains the
thick ascending limb
14. where is the distal tubule located in the cortex
15. what are collecting ducts distal tubules from around 6 nephrons that converge
into a single collecting duct and converge to eventually
empty into the renal pelvis
16. what are the 2 types of nephrons cortical and juxtamedullary (JM)
17. What percent of nephrons are cor- 85% cortical, 15ish% JM
tical and what percent of nephrons
are JM
18. where are cortical nephrons located in outer cortex
19. where are JM nephrons located deep in the cortex
20. what are JM considered and impor- salt conserving nephrons and are important for urine
tant for concentration
21. what happens when circulating blood flow will be directed towards the JM nephron to
blood volume is reduced in relation help conserve ECF volume
to JM nephrons
22. What are 4 important terms to filtration, reabsorption, secretion, and excretion
know when it comes to the kidney
23. what is filtration separation of substances and extra fluid from the
blood stream, makes initial filtrate

24. what is reabsorption mvmnt of substances from the initial filtrate in the
renal tubules back into the blood stream
25. what is secreation substances moving from the bloodstream into the re-
nal tubules, ultimately become part of urine
26. what is excretion removal of waste substances from the body in urine
27. what is the initial step in urine for- filtration of plasma in glomeruli
mation
28. how many L a day does the 150-200 L
glomerulus filter
29. What is glomerular filtration rate rate at which fluid is filtered through the glomeruli into
GFR bowmans capsule
30. what does GFR reflect overall kidney function
31. what is the filtration-reabsorption excretion of most solutes is determined by how much
model is reabsorbed
32. what does the excretion of some secretion across nephron epithelia
solutes like K+ and H+ require
33. where are reabsorption rates high high proximally and fine tuned distally
and where are they fine tuned
34. What percent of total CO do the kid- 20-25%
neys recieve
35. why do the kidneys receive such a high rate needed to provide plasma for glomerular
large amount of total CO filtration
